nvestigating blood vessels
GLOSSARY:
Artery
Elastic recoil
Pulse
Valve.
Vein
Artery
Carries oxygenated blood away from the heart, expect for the pulmonary artery
The lumen is small and narrows
Thick walls
Presence of muscles walls
Veins
Carries oxygenated blood from the body parts to cells expect for pulmonary vein
Luman is large
Thin walls
Presence of valves to avoid back flow of blood
Capillaries
it takes care of the diffusion of gasses and nutrients from blood to cells of body
Very small lumen
Very thin walls
Semi permeable walls for they transportation of gases and nutrients
